Problem T3.10 has a small programming part.  Please familiarize yourself with the plotting routines for homework #4.  [[Homework 4 Solutions|My posting might be helpful to you]].

{{{#!wiki note

 For problem T3.10(d), please note that you should submit the source code and the plot as well.

 * Be sure to include units on the axes.
 * Considering that some of you had a slow start for the plotting part, please indicate how many of the lost points (if you had lost any out of the total 30 points — 20 points for HW4.4 and 10 points for HW4.5, which was half analytic and half numeric) of the programming part of HW #4 you like to get back.  If your solution to T3.10(d) is good, then '''you will get those points back''' in proportion to how good a job you do in T3.10(d).  But, you need to ask for them in your solution to T3.10(d)!

Please note that these equations are implied for problem 1(b).  The conduction band dispersion ($\varepsilon_c(k)$) and the valence band dispersion ($\varepsilon_v(k)$) are given by:

$$ \varepsilon_c(k) = E_c + \frac{\hbar^2(k - k_c)^2}{2m_n^*} $$

{{{#!wiki
$$ \varepsilon_v(k) = E_v - \frac{\hbar^2(k - k_v)^2}{2m_p^*} $$
}}}

Here, $k$, $k_c$ and $k_v$ are to be interpreted as ''vectors.''
